Nine Muses have clearly stepped up their game as you can see in the second MV teaser for their summer track, "Hurt Locker."

It's an upbeat dance track to which the girls dance their hearts out in complete unison, dressed in the same outfit. �They dance on top of containers, perhaps in relation to their lockers of hurt...?

It's sounding good so far! �Stay tuned for the full release on July 2.
